According to research conducted by Barbara Drake at Ohio State University’s College of Food, Agricultural, and Environmental Sciences, the three main enemies of maple syrup are air, time, and temperature. Even if the container hasn’t been opened, the university researchers recommend placing your maple syrup in the refrigerator immediately after purchase. “If this is not possible, consider freezing the syrup,” states the report. Maple syrup packaged in tin or glass can be stored for up to one year in the refrigerator in its original container. But because plastic ‘breathes,’ the OSU experts advise repackaging an unopened or opened plastic syrup bottle into a glass jar if you plan to store it for more than three months. “If excess water is present, or if containers are not clean when filled, bacteria, yeast, or mold may grow during storage,” the study says. “Do not simply remove the mold and reheat the product. Some microorganisms produce toxins as they grow, and these toxins could make you sick. The product should be discarded.”
